Definitions
- the present invention is directed to latching actuators and in particular to the systems that control them.
- valves of the latching variety i.e., valves whose actuators require power to open or close the valve but not to keep it open or closed.
- the use of valves that employ such actuators has greatly extended the feasibility of employing battery-operated systems. Still, such systems would be more attractive if battery longevity could be extended further.
- the present invention achieves this result by reducing the energy waste that usually occurs in driving the actuator's armature.
- the approach employed by the invention involves determining when the armature has reached the end of its travel.
- actuator-coil drive ends when it has. This can reduce energy consumption greatly, because coil-drive duration thereby does not always need to be long enough to meet worst-case requirements. This can result in a significant battery-longevity increase.
- the drive applied to the actuator coil is increased if the armature has not reached the end of its travel within a predetermined duration. This allows less coil drive to be used ordinarily, since the coil drive does not always need to be great enough to overcome the resistance that can occasionally result from, for instance, accretion of foreign matter. This coil-drive reduction, too, can contribute to longevity.
- FIG. 1 is a cross-sectional view of a latching valve on which a piezoelectric transducer has been mounted
- FIG. 2 is a block diagram of a control system for the valve's actuator.
- FIG. 1 shows in cross section a valve system 10 that includes a latching actuator.
- the actuator includes a coil 12 wound on a bobbin 14 mounted in an actuator housing 16 .
- a latching magnet 18 mounted on the bobbin 14 acts through a rear pole piece 20 to hold an armature 22 in an upper position against the force that a return spring 24 exerts on a shoulder 26 formed near the armature's lower end.
- a resilient valve member 28 at the bottom of the armature is spaced from a valve seat 30 formed about a valve inlet 32 . Fluid can therefore flow through inlet 32 and an annular cavity 34 to the valve's outlet 36 .
- Terminal 38 is in ohmic contact with the conductive housing 16 , which a contact spring 39 in turn connects to one end of the coil 12 .
- a lead 40 connects the coil 12 's other end to terminal 37 , and a non-conducting bushing 41 insulates terminal 37 from the housing 16 .
- the drive voltage's polarity is such that the resultant magnetic flux, guided largely by the ferromagnetic housing 16 , rear pole piece 20 , and front pole piece 42 , opposes that of the permanent magnet 18 .
- This breaks the magnet 18 's hold on the armature 22 and allows the return spring 24 to urge the valve member 28 onto the valve seat 30 .
- the return spring keeps it closed without any further assistance from the coil; the armature 22 's increased distance from the magnet makes the magnetic force on the armature 22 less than that of the return spring 24 .
- control circuits that operate it typically discontinue current flow after the valve has reached the desired state. Since the time required for the valve to reach the desired state can vary widely, conventional control circuits make the current-flow duration relatively long so that it will be adequate for worst-case conditions. Since most actuations are not performed under worst-case circumstances, though, coil drive typically continues for some time after the valve reaches its stable position. This is a waste of battery energy. To reduce this waste, a system that employs the present invention monitors the armature to determine whether the armature has reached its endpoint, and it stops applying coil drive when that occurs. To this end, the illustrated embodiment takes advantage of the sound that the armature makes when it reaches either end of its travel.
- the illustrated embodiment's sensor is a piezoelectric transducer 44 that responds to vibrations in the housing wall.
- the piezoelectric element 44 's size and shape have typically been so chosen as to maximize its response to the predominant frequency components, and it normally is mounted in a location where the sounds to be detected are greatest in amplitude or most distinguishable from noise.
- a terminal 46 provides electrical communication to one of the transducer 44 's electrodes through a contact spring 48 that a plastic cap 49 secured to the housing holds in place.
- the transducer 44 's other electrode can share terminal 38 with the coil because the transducer is secured to the housing 16 by conductive bonding between the housing and that electrode.
- a control circuit for the valve includes a sensor amplifier and envelope detector 50 , which receives the transducer output.
- the amplifier and envelope detector 50 includes an amplifier tuned to the expected sound's predominant (typically ultrasonic-range) frequency components, rectifies the resultant filtered signal, and low-pass filters the result to produce an output representative of the tuned-amplifier output's envelope.
- the armature 22 reaches an endpoint and causes housing vibration, the resultant envelope value exceeds a threshold that a comparator 52 applies. Since in the illustrative embodiment the sonic amplitude is higher when the valve opens than when it closes, a microcontroller 54 sets a comparator threshold whose value when the valve is being opened is different from the value it has when the valve is being closed.
- a microcontroller 54 may operate the valve in response to triggering by an object sensor 56 . For example, it may open the valve when the sensor detects user's leaving the flusher's vicinity, and it may then close it once the valve has been open for a predetermined duration. To open the valve, the microcontroller sets an OPEN signal applied to a valve-driver circuit 58 . This causes that circuit to drive current through the actuator 60 's coil in the direction that will cause the valve to open.
- comparator 52 's output initially indicates that amplifier 50 's output is less than the threshold, so the amplifier is not receiving sound of a magnitude consistent with the armature's reaching the end of its travel.
- the microcontroller 54 therefore keeps the OPEN signal asserted.
- comparator 52 's output changes in response to the sound made by the armature 22 at the end of its travel.
- the microcontroller de-asserts its OPEN output and thereby causes the valve driver 58 to stop applying drive current to the actuator 60 's coil.
- the result usually is that the current-flow duration has been much less than the time required to open the valve under worst-case conditions, so the system has saved considerable energy.
- the microcontroller 54 asserts its CLOSE output and thereby causes the valve driver 58 to drive the actuator 60 in the opposite direction. Again, the microcontroller allows current flow only until comparator 52 informs it that the armature has reached the end of its travel.
- the invention can be used to control not only the drive signal's duration but also its magnitude.
- a coil-drive level high enough for ordinary operation may occasionally be inadequate, and the coil-drive level can be increased if the armature fails to reach the endpoint.
- One way to increase the coil-drive level is to increase the voltage on capacitors discharged through the actuator coil.
- FIG. 2 depicts the valve driver 58 as being powered by a battery 62 .
- the valve driver 58 typically includes energy-storage capacitors, which the battery 62 charges up between actuations through an inductor L 1 and a Shottky diode D 1 .
- the microcontroller 54 asserts its OPEN or CLOSE signal, the driver discharges the capacitors through the actuator 60 's coil.
- the voltage of battery 62 itself that determines the voltages to which the capacitors will be charged, and this in turns determines coil current and thus armature force.
- the illustrated embodiment therefore uses a battery-voltage level that is adequate for normal situations but not for more-difficult ones.
- the microcontroller 54 turns the valve driver off temporarily when the predetermined maximum current-flow duration is reached, and it begins to pulse a transistor Q 1 through a current-limiting resistor R 1 . During each pulse, the transistor draws current from the battery through inductor L 1 . Because of diode D 1 , though, it does not discharge the valve driver's capacitors. At the end of each pulse, transistor Q 1 turns off, and the resultant electromotive force in inductor L 1 causes current to continue to flow and thereby charge the drive circuit's capacitors through diode D 2 even if those batteries' voltage exceeds that of the battery 62 . So those capacitors can be charged to voltages that exceed the battery's.
- a comparator 64 compares the capacitor voltage to a level that microcontroller 54 sets. In response to the comparator's resultant output, the microcontroller increases the pulses' duty cycle if the capacitor voltage is less than the threshold, and it decreases their duty cycle if the capacitor voltage exceeds the threshold.
- the threshold is set higher than the battery voltage, so the force on the armature is greater and more likely to open or close the valve when the microcontroller then turns the valve driver on again.
- the illustrative embodiment is only one of many that can employ the present invention's teachings.
- a sonic sensor in particular, an ultrasonic transducer-other ways of detecting the end of armature travel can be used instead.
- the illustrated embodiment controls coil-drive duration both when the valve is being opened and when it is being closed, some embodiments may control that duration only during opening or only during closing. And latching-actuator systems that operate mechanisms other than valves can also benefit from the present invention's teachings.
- the sonic signal could be sampled and compared by signal processing with a stored waveform known to be characteristic of the armature's reaching one of its endpoints.
- the stored signal may be different for different endpoints, and there may be circumstances in which it will be considered valuable to use such a comparison to distinguish between the actuator's two states.
- the present invention can thus be employed in a wide range of embodiments and constitutes a significant advance in the art.
